Hi everyone,

 

This is more stats-related question than a technical SAS-coding question, but maybe there is an option in the proc logistic procedure to generate the output I'm looking for.

 

I used a logistic regression model, proc logistic procedure, to model the probability of a binary event occuring (=1):

Event_ID Probability/ Expected Actual/ Event_Occured
123 0.98 1
223 0.67 1
224 0.012 1
225 0.0506 1
321 0.0006 0
322 0.103 0
323 0.0089 0
342 0.46 1
564 0.69 1
597 0.89 1
598 0.76 1
601 0.0045 0
689 0.15 0
756 0.68 1
897 0.72 1
899 0.089 0
1001 0.23 0
1501 0.88 1
8997 0.45 1

 

Is there an efficient way to graph the expected (predicted probabilities) vs actual (event results) to give an indication on how well the model is performing ?

 

Thank you !

Yes, use the EFFECTPLOT statement:

ods graphics on;
proc logistic data=sashelp.class;
model sex = height;
effectplot;
run;

What is ANOVA?

ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
